A Modern B2B Studio Built for Operator Growth

3 Oaks Gaming is a B2B HTML5 casino content studio launched in 2021 and headquartered in Douglas, Isle of Man. The company develops video slots, table games, and scratch card titles designed for regulated markets across Europe and globally. Since launch, the studio has expanded its catalogue to more than 100 titles and built a reputation for pairing strong math models with an integrated promotional toolkit.

The company is licensed by the UK Gambling Commission, the Isle of Man Gambling Supervision Commission, Romania's National Gambling Office (ONJN) and the Hellenic Gaming Commission, and holds a Malta Gaming Authority recognition notice, giving operators the compliance credibility to deploy 3 Oaks content in the most competitive regulated markets. Titles carry third-party RNG certification and are built natively in HTML5 for seamless play across desktop, iOS, and Android without plugins or downloads.

3 Oaks Gaming is one of the studios you can reach through the OHS Gaming casino game aggregator, so its titles sit in your lobby alongside the rest of the catalogue you connect.

Key Provider Features

Everything operators need to deploy and grow a 3 Oaks Gaming offering on the OHS Gaming platform.

Jackpot Aggregator System

3 Oaks Gaming operates a proprietary jackpot aggregator that runs across the full catalogue. Operators configure jackpot pool sizes, contribution rates, and display rules from a single back-office interface. The system pools prize contributions across player sessions and titles, delivering network jackpot moments that drive cross-game player activity.

Operator-Configured

Free Rounds Management Tool

A dedicated free rounds tool lets operators assign bonus spins on specific 3 Oaks titles directly from the back office. Spins are credited at a defined bet level, with no requirement for custom game configurations. The tool integrates with bonus wallets and is compatible with most iGaming platform bonus engines.

Bonus Engine Ready

Tournament Engine

The built-in tournament engine enables operators to run competitive prize events across 3 Oaks titles. Tournaments are scored by win amount, multiplier, or leaderboard position. Prize structures, entry conditions, and duration are fully configurable, giving operators a retention tool that requires no additional platform development.

Player Retention

Buy Feature and Regulated-Market Licensing

Selected 3 Oaks titles include a Buy Feature option, allowing players to purchase direct access to the bonus round at a set multiplier of the base bet. With licenses in the UK, the Isle of Man, Romania and Greece and an MGA recognition notice, 3 Oaks can supply operators in those markets once each title is certified for the jurisdiction.

Technology

Core Game Mechanics

The engineering foundations that power every 3 Oaks Gaming title on the OHS Gaming platform.

Expanding Symbol Free Spins

Multiple 3 Oaks video slots use an expanding symbol mechanic in the free spins round. Before free spins begin, one symbol is randomly selected. That symbol expands to cover entire reels on each free spin, dramatically compressing the symbol set and producing the dense coverage needed for large line wins. This mechanic appears in Book of the Fallen and several other catalogue titles.

  • Random expanding symbol selection pre-round
  • Full-reel expansion across all active reels
  • Retriggerable free spins on selected titles

Cascading Reels with Multiplier Growth

Several 3 Oaks titles deploy cascading reel mechanics, where winning symbols are removed and replaced by new symbols falling from above. Each consecutive cascade within a single spin increases a running multiplier, rewarding extended win chains with escalating payouts. The Greatest Catch uses this architecture to create session-length engagement through compounding win sequences.

  • Symbol removal and cascade refill on each win
  • Multiplier increments with each consecutive cascade
  • Free spins round with elevated starting multiplier

Respin and Hold Mechanics

Classic 3 Oaks titles use a respin-and-hold architecture where landing a defined symbol combination triggers a held-reel respin sequence. Held symbols lock in position while the remaining reels spin again, building toward a full-reel fill that pays the jackpot prize. Hot Triple Sevens and Fire and Gold use this mechanic to deliver high-anticipation bonus activation moments.

  • Symbol-triggered held-reel respin activation
  • Progressive fill toward full-reel jackpot payout
  • Buy Feature access on selected respin titles

3 Oaks Gaming API Integration

Operators connect to the full 3 Oaks Gaming catalogue through OHS Gaming's single unified API, with no separate agreement with 3 Oaks Gaming required. Integration includes the complete promotional layer (jackpot aggregator, free rounds manager, tournament engine) and back-office reporting, so new titles and promotional tools become available automatically as they are added to the catalogue.
